VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 697,363, dated April. 8, 1902.

Application filed September 4, 1901- Serial No. 74,281. (No model.)

To ail whom it may concern:

Be it known that I, IGNAOIO O. RAMIREZ, a citizen of the Republic of Mexico, and a resident of Puebla, Mexico, have invented a new and Improved Ventilator, of whichthe following is a full, clear, and exact description.

This invention relates to a ventilator which by means of evaporation serves to introduce into an apartmentacurrent of cool and pure air.

The invention, generally stated, involves a vertically-extendin g tube or conduit, with ab sorbent material therein, in which tube is induceda current of air passing from the atmosphere into the apartment, such current being not only fresh, but being cooled by the evaporation which takes place in the tube.

This specification is a specific description of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section of the invention. Fig. 2 is a plan view of the same. Fig. 3 is afragmentary side view thereof, and Figs. 4 and 5 are details of the spider which supports the absorbent threads.

.The tube or conduit forming themain or body portion of the apparatus is preferably arranged in two parts, (designateda and 1),) of which the part a is the major or upper portion and the part b the lower portion, the two parts being rigidly connected together by vertically-extending stringers c.

(1 indicates a sleeve or thimble whichis set loosely over the adjacent ends of the parts a and b of the tube and is held in proper position by means of a bead 5', formed on the tube-section b. This'sleeve or thimble may be raised fully on the section a, so as to eX- pose the interior of the tube.

d indicates a horizontal discharge branch of the thimble d, said branch being provided with a damper d to regulate the'draft.

The tube-section b is provided at its bottom with a reservoir 6 for containing the dripwater. According to the preferred arrangement, the tube-section b is set into the reservoir e and communicates freely therewith at its bottom, so as to hold the drip-water, as indicatedby the broken lines in Fig. 1. V

f indicates a wind-break which is placed in the upper portion of the tube-section b and which is formed with an orifice f, permitting the drip-water to pass the wind-breakf. This element, however, breaks the current of air as it passes downward and deflects it outward through the branch d of the thimble (1.

At the upper end of the tube-section a is erected a cup or reservoir g, which is adapted to be kept filled or partly filled with water. Into this cup project the upper ends of absorbent cords or threads h, which pass longitudinally through the tube-section a. These cords are held stretched with a moderate degree of tension between spiders t and 7c, the former being arranged at the upper end of the tube-section a and the latter at the lower end thereof within the thimble d. These spiders may be of any construction desired, so long as they hold the absorbent threads properly within the tube a and permit the upper ends of the threads to project into the cup g. I prefer, however, to construct the spiders as shown in Figs. 4: and 5-that is to say, with an annular rim having cross-pieces 'i, said rim and cross-pieces being provided with upwardly-projected pins 71 to which the threads It may be attached. The spider c is provided with radially-projected studs '6 adapted to engage the top of the tube a, and these studs have slight shoulders i formed on their under sides, which prevent the lateral displacement of the spider. The bottom spider k is of essentially the same construction as the spider t', excepting that the shoulders t are dispensed with. The bottom spider 7c bears against the under side of the lugs or flanges Z, secured to the stringers c, as shown. The absorbent threads or cords -h are suitably fastened to the spiders 'i and It, so that the threads will be stretched between them, and the upper ends of the threads are turned over into the cup g. The thread should be of the most absorbent material obtainable, and if ordinary small cords are employed they should be first boiled or otherwise treated to remove all fatty substances, thus to increase the absorbent capacity of the threads. It will be seen that the spiders, with their circular rims and diametrical cross pieces, dispose the threads in the form of a tube with diametric partitions extending through it. As the threads absorb the moisture from the cup g and this moisture is transmitted by capillary attraction down the cords or threads the entire interior of the tube a becomes pervaded with the moisture, and this induces evaporation, which lowers the temperature within the tube. The temperature within the tube being thus lowered, a downward current will be induced, and this current will enhance the evaporation, and thus in turn increase the downward current. The damper 61 being opened,this current will flow out of the branch (1 into the apartment. The upper end of the tube-section a may be placed in communication with the atmosphere or with any other source of pure air. Such water as may drip from the threads h will fall onto the windbreakf, and thence into the receptacle 6. If desired, a small pump or other means may be provided for returning the water from the receptacle 6 to the cup g, or, if desired, the water from the receptacle may be permitted to flow out thereof to any point of waste and the cup g kept full by a properly-controlled flow from the source of feed.

Various changes in the form, proportions, and minor details may be resorted to without departing from the spirit and scope of my invention. Hence I consider myself entitled to all such Variations as may lie within the scope of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of two tube-sections, means connecting the sections together but holding them spaced from each other, a thimble mounted loosely on the sections and exof, a drip-cup in the lower tube-section, and

an orificed wind-break arranged above the drip-cup and below the discharge-orifice of the thimble.

3. The combination of two tube-sections, means connecting the sections together but holding them spaced from each other, a thimble mounted loosely on the sections and extending between their adjacent ends, said thimble having a discharge-orifice, an absorbent material arranged in the upper tube-section, a drip-cup in the lower tube-section, an orificed wind-break arranged above the dripcup and below the discharge-orifice of the thimble, and a cup at the top of the upper tube-section, the upper ends of the absorbent material being turned over the upper end of the upper tube-section and dipped into the cup, such cup serving to receive the primary supply of liquid.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

IGNACIO C. RAMIREZ.
